Steel DP450 vs DP600
Steel · grade comparison
Steel DP450 and DP600 are both steel grades. DP600 is the stronger of the two: yield strength 380 MPa (55.1 ksi) against 300 MPa (43.5 ksi) for DP450, about 27% more; tensile strength follows at 640 MPa (92.8 ksi) vs 500 MPa (72.5 ksi). In exchange, DP450 is the more ductile: elongation 29% versus 24% for DP600, and DP600 is harder (190 HB vs 143 HB). On the shop floor, DP450 machines more easily (good vs fair) and DP450 welds better (82 vs 72 out of 100).
DP450Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
DP600Choose it when strength drives the design.
DP450 vs DP600: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all steel grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

DP450 vs DP600 — frequently asked
Is DP600 stronger than DP450?
Yes. DP600 has a typical yield strength of 380 MPa (55.1 ksi) against 300 MPa (43.5 ksi) for DP450 — about 27% more. Tensile strength is 640 MPa (92.8 ksi) vs 500 MPa (72.5 ksi).
Which is cheaper, DP450 or DP600?
Both sit in the same relative cost tier ($, budget); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, DP450 or DP600?
DP450. Its machinability rates good (55/100) against fair (45/100) for DP600; for welding the order is DP450 first (very good, 82/100) then DP600 (very good, 72/100).
